A rock is any type of normally happening solid mass or aggregate of minerals or mineraloid matter. It is classified by the minerals included, its chemical structure as well as the way in which it is developed. Rocks create the Earth s outer strong layer, the crust, and also many of its inside, with the exception of the liquid external core and pockets of lava in the asthenosphere.
Rocks are normally grouped into three major groups: igneous rocks, stratified rocks as well as metamorphic rocks. Igneous rocks are developed when magma cools down in the Planet s crust, or lava cools on the ground surface or the seabed. Stratified rocks are formed by diagenesis or lithification of sediments, which subsequently are developed by the weathering, transport, and deposition of existing rocks. Metamorphic rocks are formed when existing rocks go through such high stress and temperature levels that they are transformed– something that occurs, as an example, when continental plates collide.: 31– 33, 134– 139 The scientific study of the character as well as origin of rocks is called petrology, which is an essential subdiscipline of geology.

Serial Cleaner

In Serial Cleaner we purify on behalf of Killern crime, eliminate traces and let evidence disappear. We have to do all this, while the police already secure the scene. Even whole bodies we drag from it when the officials are looking straight in the other direction. In the core, Serial Cleaner is a mechanical simple, but in places quite demanding laugh in the top-down perspective, which is characterized by the twenty varied scene in addition to its macabrene humor. The story is especially told in short episodes between the levels that play in our own apartment, which is strongly reminiscent of Hotline Miami.

BlackSad: Under the Skin

The Detective Adventure BlackSad is based on the COMICREAR of the same name and plays in the New York of the 50s, but in a world populated by anthropomorphic animals. We assume the role of the private detective John BlackSad and should enlighten the murder of a box club owner and the sudden disappearance of an emerging boxer. BlackSad is characterized by its moody graphic style, its great jazz soundtrack and the thrilling film noir atmosphere. The gameplay consists of a mixture of puzzles, Quick Time Events and Multiple Choice dialogs. That s not necessarily creative, but solid.

Beholdder: Complete Edition

In Beholder we play a landlord in a totalitarian state. Its government calls on us to spy out our tenants and report their violations. We can do that by peeking or hiding cameras, for example, if the tenants are not at home. But we can also pay attention to the privacy of our tenants or keep their deeds for us. But then we have to expect consequences that not only affect ourselves, but also our family. So the question is, as we want to decide. The Complete Edition contains next to the main game also the DLC Blissful Sleep.

In the racing GRAVEL, we race through landscapes in off-road races ranging from the Namibias desert to Alaska s mountains. Realism is rather less, instead, it is a fun arcade racer, in the foreground grid and creative stretch design. Gravel is therefore the right thing for those looking for entertaining races in between. Simulation fans, on the other hand, lack the complexity despite good driving physics. Incidentally, in addition to the standard version, the Special Edition is also cheaper, for 3.99 euros instead of 39.99 euros.

Reus recalls gods simulations like populous or black & white. We controlled four giants whose skills we can form the world according to our ideas. On the other hand, we have no direct control over the people on our planet. Maybe they behave according to our wishes, but maybe they prefer to deal with each other to confuse each other. We can only try to direct them indirectly by changing their living conditions. If we do that and you achieve certain milestones, we thus switch new content and skills for ourselves.
